Can Food Allergies Cause Fever

Signs And Symptoms Of Food Allergies In Babies

Understanding Food Allergy

Food allergy symptoms present very differently in babies than they do in toddlers and older children, and can be easy to confuse with the symptoms of colds, sensitive skin, and teething.

Its important to be able to identify possible signs and symptoms of food allergies in babies as well as to know when to seek medical attention.

Allergic reactions happen almost immediately after eating or touching a food. In rare cases, however, reactions can happen up to 4 hours later.

Its best to feed your baby new foods on a day and time where you will be with them for a few hours afterwards.

What Can Cause Allergy Symptoms And Fever

Viral infections can cause a person to develop allergy-like symptoms alongside a fever.

One notable indication that a person has allergies is that allergy symptoms last only as long as people are experiencing an exposure to the allergen. Other causes, such as the flu or common cold, can last much longer.

Additionally, allergies cause a person to experience itchy and watery eyes. This does not typically occur alongside a cold or flu.

Oas And Nose Allergies Can Be Linked

  • Over 50% of people who are allergic to pollen also have OAS. This means 10% of all people.
  • Ragweed pollen allergy can cross-react with all melons. Also, sometimes with bananas and tomatoes.
  • Birch pollen allergy can cross-react with raw potatoes, carrots, celery and apples.
  • Grass pollen allergy can cross-react with tomato and kiwi.

Treating Food Allergy Or Intolerance

The easiest way to treat a food allergy or intolerance is to eliminate the offending food/s from the diet. Sometimes, the body can tolerate the food if it is avoided for a time, then reintroduced in small doses, particularly for food intolerances. Before you eliminate or reintroduce foods, seek advice from a specialist doctor and dietitian.

Allergies Could Cause A Fever Indirectly Though

Can Food Allergies Cause Fever And Chills

Seasonal allergies can cause your sinuses and lungs to get inflamed, explains Purvi Parikh, M.D., an allergist and immunologist with the nonprofit Allergy & Asthma Network. And that, she says, makes you more susceptible to catching viruses and bacteria which lead to infections.

Allergies also mess with an important and basic part of your immune system, says Craig Jones, M.D., medical director of otolaryngology at Mass. Eye and Ear, Cape Cod. Part of our innate immunity is the mucosal barrier in our nose and airways, he says, noting that allergies interfere with this barrier.

Another way your allergies could contribute to you developing a fever: You tend to touch your face more when you have symptoms. Simply by touching a spot, such as a shopping cart, telephone, or computer keyboard contaminated with a virus, and then rubbing the nose or eyes, a person can inoculate themselves with a germ, Dr. Jones says. Patients with allergies are much more likely to rub their eyes or nose due to itching, which puts them at additional risk.

You can develop whats known as a secondary infection from your allergies as well, says Kara Wada, M.D., an allergist-immunologist at The Ohio State University Wexner Medical Center. Secondary sinus and/or ear infections can result from severe allergies, which can cause fevers, she says.

How Do Allergies Happen

If a child with an allergy is exposed to that allergen, their immune system mistakenly believes it’s harming their body. It overreacts, treating the substance as an invader and trying to fight it off. To protect the body, the immune system makes antibodies called immunoglobulin E . These cause certain cells to release chemicals into the bloodstream to defend against the allergen “invader.”

It’s the release of these chemicals that causes allergic reactions. Reactions can affect the eyes, nose, throat, lungs, skin, and gastrointestinal tract. Future exposure to that same allergen will trigger this allergic response again.

When To See A Doctor For Fever

A fever is what happens when the body is fighting off the germs of an infection or illness and while, yes, it can be scary , its not always cause for a trip to the doctor. According to the American Academy of Pediatrics , children should be seen by their pediatrician if theyre younger than 12 weeks and have a rectal temperature of 100.4 F or higher, or have a temperature of 104 F if theyre older.

Additional reasons to call the doctor when a fever is present, according to the AAP:

  • The fever is present for more than 24 hours in a child younger than 2.

  • The fever is present for more than 3 days in a child 2 or older.

  • A child appears very ill, drowsy or is unusually fussy.

  • A child has been in a very hot place, like an overheated car.

  • A stiff neck, severe headache, severe sore throat, severe ear pain, rash or continuous vomiting or diarrhea is also present.

  • The child has had a seizure.

  • The child appears to be getting worse instead of better.

  • There are signs of dehydration present, such as dry mouth and fewer wet diapers.

  • The child already has immune system problems or is taking a steroid.

And of course, nobody knows your child better than you. If something isnt sitting well with you, feel free to give their doctor a call.

Food Allergies And Inflammation

an excerpt from The Unhealthy Truth: How Our Food Is Making Us Sick by Robyn OBrien

Robyn OBrien was not someone who gave much thought to misguided government agencies and chemicals in our food until the day her youngest daughter had a violent allergic reaction to eggs, and her world changed. OBriens book The Unhealthy Truth: How Our Food Is Making Us Sick And What We can Do About It is both a story of how one brave woman chose to take on the system and the call to action that shows how each of us can do our part to keep our own families safe.

Food Allergy Is Increasing

Allergies in general are on the increase worldwide and food allergies have also become more common, particularly peanut allergy in preschool children. About 60 per cent of allergies appear during the first year of life. Cows milk allergy is one of the most common in early childhood. Most children grow out of it before they start school.

Symptoms Of Food Allergies

  • Hives all over and swelling of the face are the most common symptoms. Hives are raised pink bumps with pale centers . They look like bug bites.
  • Mouth itching and swelling
  • Runny nose and coughing
  • Vomiting and diarrhea
  • Life-threatening allergic reactions also must have trouble breathing and/or swallowing. The medical name for this is anaphylaxis. Most of these reactions have a sudden onset within 10 to 20 minutes. All occur within 2 hours of eating a certain food. People who have had this carry an emergency kit like an Epi-Pen.

Common types of allergies include:

Airborne Allergies

  • insect sting allergy
  • medicines, such as antibiotics and some over-the-counter medicines
  • chemicals. Some cosmetics or laundry detergents can make people break out in hives. Usually, this is because someone has a reaction to the chemicals in these products. Dyes, household cleaners, and pesticides also can cause allergic reactions in some people.

Severe Food Allergy In Children

Allergic reactions, including anaphylaxis, are common, although deaths from anaphylaxis are rare. Most schools and childcare services across Australia are required to have an anaphylaxis management policy in place.Banning particular foods is not recommended as it can create a sense of complacency and is difficult to monitor and enforce. A better approach is to educate staff, students and the community about the risks associated with anaphylaxis and put strategies in place to minimise exposure to known allergens.

Fever With Allergy Symptoms

When you develop congestion, regardless of the cause, the buildup of mucus in your sinuses can be a breeding ground for bacteria. When an infection takes hold, you can be hit with a fever that can last for several days.

Congestion can be the result of sinusitis, allergies, or something more serious, such as the flu virus. Its sometimes hard to know whats causing your symptoms, because a cold or flu can mimic many of the signs of an allergy.

Discovering exactly whats causing your symptoms, even if theyre mild, is important. Once you know the cause of your symptoms, you can start an effective treatment plan. And, in the case of an allergy, you can take steps to prevent symptoms or flare-ups in the future.

The key, however, is a proper diagnosis.

What Food Allergies Look Like In Babies

The most common, and confusing, symptoms of an allergic reaction in a baby are:

  • redness around the mouth or skin that came into contact with saliva or the food
  • stomach distress such as vomiting or diarrhea
  • Runny or stuffy nose, sometimes with clear discharge
  • Redness or itchiness of the nose
  • Swelling of the face, including puffiness around the eyes

Redness around the mouth vs swelling of the face and eye area from an allergic reaction

Heres the problem – babies get redness on their face all the time from saliva irritation and when they are teething. Teething or a virus can cause hives, vomiting / diarrhea or a runny nose.

If your baby has any of the symptoms above within a couple of minutes of trying a new food OR has two or more of the symptoms above, you should seek medical attention immediately.

Very rare, severe symptoms of an allergic reaction in a baby are:

  • Coughing/wheezing
  • Swelling of the mouth, including the lips and possibly tongue
  • Fever higher than 104 degrees or lower than 97 degrees
  • Swelling of the throat and difficulty swallowing
  • Weak pulse
  • Losing consciousness

An important study showed that severe symptoms in babies under 12 months are extremely rare. The younger your baby, the less likely it is they’ll have a severe reaction.

Symptoms Of Food Intolerance

Symptoms of food intolerance can include:

  • nervousness
  • burning sensations on the skin
  • tightness across the face and chest
  • breathing problems asthma-like symptoms
  • persistent dizziness or collapse
  • becoming pale and floppy .

Several factors can influence the severity of anaphylaxis, including exercise, heat, alcohol, the amount of food eaten, and how food is prepared and consumed.To prevent severe injury or death, a person with anaphylaxis requires an injection of adrenaline . People who are considered by their doctor to be at risk of anaphylaxis are prescribed an autoinjector which contains a single fixed dose of adrenaline. They are designed to be used by non-medical people and should be administered into the outer mid-thigh muscle in the event of a severe allergic reaction. Adrenaline autoinjectors are also available directly from a pharmacy.

How To Tell If Your Symptoms Are Due To Allergies

If you think you have allergies, its a good idea to make an appointment with an allergist/immunologist, the type of doctor who treats these conditions. My patients commonly tell me that they didnt realize how miserable their symptoms were until they started medications that allowed them to breathe easier with less congestion or have an improved sense of smell, says Dr. Hui.

To diagnose a patient, the first thing we want to gather is the history so we have a clear understanding of how you feel and what your goals are for this visit, explains Dr. Hui. She asks questions like: What are you experiencing? How long has this been going on? What makes it better or worse? Have you tried anything to treat your symptoms?

Based on the information gathered from talking with you and performing a physical exam, we can actually provide some treatment options without further testing, says Dr. Hui. However, we often do pursue the allergy testing route, as this gives us more specifics.

Can Allergies Cause A Low

Allergies happen when the body overreacts to a substance it considers harmful. As a result, the immune system produces antibodies and histamine to fight off the perceived invaders, causing an inflammatory reaction that makes you feel downright lousy.

Even though seasonal allergies are sometimes called “hay fever,” they don’t usually trigger a rise in temperature, says Natasha Burgert, M.D., a board-certified pediatrician for Pediatric Associates in Overland Park, Kansas. Fevers are more likely to be viral or bacterial in nature, adds Dr. Jain.

It’s important to note that your child’s immune system works overtime to fight off allergies, which increases their susceptibility to colds, sinus infections, or viruses. Your kid can definitely run a fever while suffering from allergies, but their high temperature won’t actually be caused by the allergies.

How Are Food Allergies Treated

A child who has a food allergy should always have two epinephrine auto-injectors nearby in case of a severe reaction. An epinephrine auto-injector is a prescription medicine that comes in a small, easy-to-carry container. It’s easy to use. Your doctor will show you how. Always have two auto injectors nearby in case one doesn’t work or your child needs a second dose.

The doctor can also give you an allergy action plan, which helps you prepare for, recognize, and treat an allergic reaction. Share the plan with anyone else who needs to know, such as relatives, school officials, and coaches. Wherever your child is, caregivers should always know where the epinephrine is, have easy access to it, and know how to give the shot. Also consider having your child wearing a medical alert bracelet.

Time matters in an allergic reaction. If your child starts having serious allergic symptoms, like trouble breathing or throat tightness, use the epinephrine auto-injector right away. Also use it right away if symptoms involve two different parts of the body, like hives with vomiting. Then call 911 and have them take your child to the emergency room. Medical supervision is important because even if the worst seems to have passed, a second wave of serious symptoms can happen.

Allergy Can Be Inherited

Food allergy

Children who have one family member with allergic diseases have a 20 to 40 per cent higher risk of developing allergy. If there are two or more family members with allergic diseases, the risk increases to 50 to 80 per cent.

Most of the time, children with food allergy do not have parents with food allergy. However, if a family has one child with food allergy, their brothers and sisters are at a slightly higher risk of having food allergy themselves, although that risk is still relatively low.

How To Get Tested

A food allergy will usually cause some sort of reaction every time the trigger food is eaten. Symptoms can vary from person to person, and you may not always experience the same symptoms during every reaction. Allergic reactions to food can affect the skin, respiratory tract, gastrointestinal tract and cardiovascular system. It is impossible to predict how severe the next reaction might be, and all patients with food allergies should be carefully counseled about the risk of anaphylaxis, a potentially fatal reaction that is treated with epinephrine .

While food allergies may develop at any age, most appear in early childhood. If you suspect a food allergy, see an allergist, who will take your family and medical history, decide which tests to perform and use this information to determine if a food allergy exists.

To make a diagnosis, allergists ask detailed questions about your medical history and your symptoms. Be prepared to answer questions about:

  • What and how much you ate
  • How long it took for symptoms to develop
  • What symptoms you experienced and how long they lasted.

After taking your history, your allergist may order skin tests and/or blood tests, which indicate whether food-specific immunoglobulin E antibodies are present in your body:

Your allergist will use the results of these tests in making a diagnosis. A positive result does not necessarily indicate that there is an allergy, though a negative result is useful in ruling one out.

What Is The Outlook For People With Food Allergies

You can live a healthy life with a food allergy. If you have a food allergy, you need to carefully avoid all foods and ingredients that cause allergic reactions.

You may also need to take a nutritional supplement to replace any nutrients lost by avoiding your trigger foods. Speak with your healthcare provider or dietitian before starting a new eating plan.
